Today’s random but thought provoking science…….

If you take one kilogram of ice and melt it to complete liquid water at one degree centigrade then that requires a certain amount of heat energy.  If you then apply the exact same amount of heat energy it will be enough to heat the same one kilogram of water from zero to about eighty degrees centigrade (I should do the maths to check that one).

Atoms are made up of mostly empty space.  You are made of atoms.  You are made of mostly empty space.  If you were able to remove all this empty space then your body would occupy a volume smaller than a grain of salt.  You would not be any heavier or lighter as it is only empty space that is removed.  If we took all the empty space out of all the people on earth then the all the people would occupy roughly the volume of an apple.
